we estimate the peak electric field of the pump laser pulse to beFpump = 0.5 V nm−1in open space. For this electric field strength, Fig.2ashows the corresponding schematic energy diagram of a gold-vacuum interface (black line). As depicted by the colored lines, the potential...
Localized surface plasmon resonance (LSPR) of plasmonic nanoparticles and nanostructures has attracted wide attention because the nanoparticles exhibit a strong near-field enhancement through interaction with visible light, enabling subwavelength optics and sensing at the single-molecule level. The extremely ...

In this regard, exploring the phase diagram of complex materials at low temperature remains essential for better data interpretation from cryogenic techniques, which can yield new insights to the material study. With the advancement of high-end detectors and imaging techniques such as four-dimensional...
An image is formed from the interaction of the electrons transmitted through the specimen; the image is magnified and focused onto an imaging device, such as a fluorescent screen, on a layer of photographic film, or to be detected by a sensor such as a CCD camera. TEMs are capable of ...
